3 Customizing AF Functions N
Enables or disables the AF-ass ist beam from the EOS-dedicated 
external Speedlite.
ON: Enable
The external Speedlite emits the AF-
assist beam when necessary.
OFF: Disable
The external Speedlite will not emit 
the AF-assist beam. Prevents the AF-
assist beam from disturbing others.
IR: IR AF assist beam only
When an external Speedlite is attached, only the in frared AF-assist 
beam will be emitted. This prevents th e AF-assist light from firing as 
a burst of small flashes.
With an EX-series Speedlite equi pped with an LED light, the LED 
light will not automatically  turn on for AF-assist.
AF-assist beam firing
If an external Speedlite’s [ AF-assist beam firing] Custom Function is set to 
[ Disabled], the Speedlite will not emit the AF-assist beam regardless of this 
setting.

You can set the AF operation charac teristics and shutter-release timing 
for One-Shot AF.
: Focus priority
The picture will not be taken until 
focus is achieved. Effective when you 
want to achieve focus before 
capturing the shot.
: Release priority
Priority is given to the timing of 
shutter release instead of achieving 
focus. This gives priority to capturing 
the image rather than achieving 
correct focus.
Note that the picture will be taken 
even if focus has not been 
achieved.

If focus cannot be achieved with autofocus, you can have the camera 
keep searching for the correct focus or have it stop searching.
ON: Continue focus search
If focus cannot be achieved with 
autofocus, the lens is driven to search 
for the correct focus.
OFF: Stop focus search
If autofocus starts and the focus is far 
off or if focus cannot be achieved, the 
lens drive will not be performed. This 
prevents the lens from becoming 
grossly out of focus due to focus 
searching.

Lens drive when AF impossible
Super telephoto lenses, etc., with a wide focusing drive range can become 
grossly out of focus during focus search, taking more time to achieve focus 
next time. Setting [ Stop focus search ] is recommended.

You can change the number of manually selectable AF points. If 61-
point automatic selection AF is set, the Area AF frame (entire AF area) 
will be used for AF regardless of the setting below.
: 61 points
All AF points will be manually 
selectable.
: Only cross-type AF points
Only cross-type AF points will be 
manually selectable. The number of 
selectable cross-type AF points will 
differ depending on the lens.
: 15 points
Fifteen major AF points will be 
manually selectable.
: 9 points 
Nine major AF points will be manually 
selectable.
Selectable AF point
With a lens from Groups F to H (p.103-104), the number of manually 
selectable AF points will be fewer.
Even with settings other than [ 61 points], AF point expansion (manual 
selection  ), AF point expansion (manual selection, surrounding points) 
and Zone AF (manual selection of zone) are still possible.
 When you press the < S> button, the AF points which are not manually 
selectable will not be displayed in the viewfinder.

: Separate AF pts: Area+pt
The AF area selection mode and AF point (or zone) can be set 
separately for each camera orientatio n (1. Horizontal, 2. Vertical with 
the camera grip at the top, 3. Vertical with the camera grip at the 
bottom).
When you manually select the AF area selection mode and AF point (or 
zone) for each of the three camera orientations, they will be set for the 
respective orientation. Whenever you change the camera orientation 
during shooting, the camera will switch to the AF area selection mode 
and manually-selected AF point (or zone) set for that orientation.
: Separate AF pts: Pt only
The AF point can be set separately for each camera orientation 
(1. Horizontal, 2. Vertical with the camera grip at the top, 3. Vertical 
with the camera grip at the bottom). While using the same AF area 
selection mode, the AF point will  switch automatically for the 
respective camera orientation.
When you manually select the AF point for each of the three camera 
orientations, it will be recorded fo r the respective orientation. During 
shooting, the manually-selected AF  point will switch to match the 
respective camera orientation. Even if you change the AF area 
selection mode to Manual select.:Spot AF, Manual selection:1 pt AF, 
Expand AF area: , or Expand AF area:Surround, the AF point set 
for the respective orient ation will be retained.
If you change the AF area selection mode to Zone AF (manual 
selection of zone), the zone will  switch to match the respective 
camera orientation.
 If you clear the camera settings to  their defaults (p.70), the setting will be 
[ Same for both vert/horiz ]. Also, your settings for the three camera 
orientations (1, 2 and 3) will be cleared and all three will revert to Single-
point AF (Manual selection) with the center AF point selected.
 If you set this and later attach a lens from a different AF group (p.100-
104, particularly Group H), the setting may be cleared.

You can set the AI Servo AF’s starting AF point for when the AF area 
selection mode is set to Auto selection: 61 pt AF.
: Initial   AF pt selected
AI Servo AF will start with the 
manually-selected AF point when the 
AF operation is set to AI Servo AF 
and the AF area selection mode is set 
to Auto selection: 61 pt AF.
: Manual   AF pt
If you switch from Manual select.:Spot AF, Manual selection:1 pt AF, 
Expand AF area: , or Expand AF area:Surround to Auto selection: 
61 pt AF, AI Servo AF will start with the AF point that was manually 
selected before the switch. Convenient if you want AI Servo AF to 
start with the AF point which was selected before the AF area 
selection mode was switched to Auto selection: 61 pt AF.
After you set the AF area selection mode to Auto selection: 61 pt AF 
with the [83: Custom Controls ] menu’s [Metering and AF start ] 
(p.418), [Switch to registered AF func. ] (p.420), or [Register/
recall shooting func] (p.425), you can press the assigned button 
during Manual select: Spot AF, Manual selection: 1 pt AF, Expand 
AF area: , or Expand AF area: Surround to switch to AI Servo AF 
using Auto selection: 61 pt AF instead of the AF point used 
immediately before.
AUTO: Auto
The AF point which AI Servo AF starts with is set automatically to 
suit the shooting conditions.
Initial AF Point,   AI Servo AF
When [ Manual   AF pt ] is set, AI Servo AF will start with the zone 
that corresponds to the manually selected AF point, even if you switch AF 
area selection mode to Zone AF (manual selection of zone).

EOS iTR* AF executes autofocus  by recognizing faces and subject 
colors. EOS iTR AF works when the AF area selection mode is set to 
61-point automatic selection AF or Zone AF (manual selection of zone).
* intelligent Tracking and Recognition: The function that the metering sensor 
identifies the subject to make the AF points tracking it.
ON: Enable
The AF point is automatically 
selected based not only on AF 
information, but also faces and other 
details. 
In AI Servo AF mode, the camera remembers the color at the position 
it focused on first, then continues to track and focus on the subject by 
switching AF points to track that color. This makes it easier to keep 
track of the subject than when only AF information is available.
In One-Shot AF mode, EOS iTR AF makes focusing on people 
easier, so you can perform shooting with priority on composition.
OFF: Disable
AF points are automatically selected based only on AF information. 
(The AF will not use information about faces, subject colors and 
other details.)
Auto AF point selection: EOS iTR AF
 If [Enable ] is set, the camera may take longer to focus than when 
[ Disable ] is set.
 Even if you set [ Enable], expected result may not be obtained depending 
on the shooting conditions and subject.
 Under light so low that the EOS-dedicated, external Speedlite emits the 
AF-assist beam automatically, AF points are selected automatically 
based only on AF information.
 Face detection may not work if the face is small or under low-light 
conditions.

During manual AF point selection, t he selection can either stop at the 
outer edge or it can cycle around to the opposite side. This function 
works in AF area selection modes other than Zone AF (manual 
selection of zone), and 61-point automatic selection AF (works with AI 
Servo AF).
: Stops at AF area edges
Convenient if you often use an AF 
point at the periphery.
: Continuous
Instead of stopping at the outer edge, 
the selection of AF point continues to 
the opposite side.
